Description

Technical Field

[0001] This utility model belongs to the field of refrigerator technology, and specifically relates to a novel refrigerator. Background Technology

[0002] Refrigerated display cases, as commonly used refrigeration and preservation equipment, are widely used in commercial retail and home storage. Their structural strength, insulation performance, ease of use, and refrigeration efficiency are core indicators for evaluating product quality. Currently, most traditional refrigerators on the market use a combination of ordinary steel plates and plastic inner liner, resulting in poor insulation and easy cold air leakage. This not only increases energy consumption but also affects the preservation quality of stored items. Furthermore, the return air pipe layout of traditional refrigerator systems is relatively simple, leading to low heat exchange efficiency with the inner liner and hindering improvements in refrigeration performance.

Detailed Implementation

[0013] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] like Figure 1-4As shown, the new type of refrigerated cabinet includes a cabinet body 1 and a cabinet door 2. The cabinet body 1 includes an outer shell 3 and an inner liner 4. The inner liner 4 is located inside the outer shell 3. A cover 5 is connected to the lower back of the outer shell 3. An installation chamber 6 is formed between the cover 5 and the outer shell 3. A refrigeration system 7 is installed in the installation chamber 6. The refrigeration system 7 includes a return pipe 8, which is located between the inner liner 4 and the outer shell 3 and is close to the inner liner 4. A foam layer made of polyurethane foam material is filled between the inner liner 4 and the outer shell 3. The inner liner 4 is made of ABS plastic, and the outer shell 3 is made of galvanized sheet. The cabinet structure made of the inner liner 4, outer shell 3, and foam layer has high strength, good heat insulation performance, and good sealing performance. The refrigeration system 7 adopts the refrigeration system 7 used in traditional refrigerated cabinets (generally including components such as a compressor, condenser, expansion valve, and evaporator), which can be directly purchased from the market.

[0017] Furthermore, the return pipe 8 includes a heat-conducting pipe that bends back and forth, and the heat-conducting pipe is in close contact with the inner liner 4. A heat-conducting plate 20 can be installed between the heat-conducting pipe and the inner liner 4. The heat-conducting plate 20 forms an evaporator commonly used in the refrigeration system 7, which can improve the heat exchange efficiency between the return pipe 8 and the inner liner 4.

[0018] Furthermore, the inner liner 4 is fixedly connected to a drain pipe 9, which extends outside the cabinet 1. A water collection box 21 is placed in the installation chamber 6, and the lower end of the drain pipe 9 extends into the water collection box 21. The pipe 22 (the end of the return air pipe) in the refrigeration system 7, whose temperature rises after heat exchange with the inside of the cabinet 1, is immersed in the water collection box 21. This allows the heat from the pipe to automatically evaporate the water in the water collection box 21, avoiding the need for manual drainage, and also cools the pipe, improving refrigeration efficiency.

[0019] Furthermore, the cover 5 is provided with heat dissipation holes 10 and an inspection port, which is covered by a rear cover 11. The heat dissipation holes 10 ensure the stable operation of the refrigeration system 7, and the inspection port facilitates the installation, inspection, and maintenance of the refrigeration system 7.

[0020] Furthermore, the cabinet door 2 includes a panel 12 and an inner lining panel 13, which are bonded together. The panel 12 is connected to the outer shell 3 by several hinges. The panel 12 is made of galvanized sheet, and the inner lining panel 13 is made of ABS plastic.

[0021] Furthermore, a sealing strip 14 is installed around the perimeter of the inner lining panel 13. The sealing strip 14 improves the airtightness of the refrigerator and prevents cold air leakage. The cabinet door 2 can be connected to the cabinet body 1 through a conventional refrigerator door closing method such as magnetic attraction.

[0022] Furthermore, a plurality of inner boxes 15 are installed on the inner lining plate 13. The inner boxes 15 can also be used to place items. Slots are provided on both sides of the inner boxes 15, and insert plates are provided on the inner lining plate 13 for inserting into the slots, so that the inner boxes 15 can be removed for cleaning and maintenance.

[0023] Furthermore, the cabinet 1 is provided with several trays 16, and the two sides of the trays 16 are respectively placed on several support bars 17, which are fixedly connected to the inner liner 4. The trays 16 allow for layered placement of items inside the cabinet 1, improving the space utilization rate inside the cabinet 1.

[0024] It is worth mentioning that the technical features of the refrigeration system 7 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be adopted by conventional choices in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0025] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
